SPECIFICATION formingpart of Letters Patent No. 249,279, dated November8, 1881.

Application filed May 2,1881. (No model.)

To all whom it may concern:

Be it known that I, EDWARD F. WHITE, ot' Weymouth, county otNorfolk, andState of Massachusetts, have invented a new and use-1 ful Improvement inMachines for Pricking, Trimming, and Channeling Soles, of which thefollowing description, in. connection with the accompanying drawings, isa specification.

shown in the said patent, movable horizon- This invention is animprovement upon United States Patent .to J, B. Turner, No. 215,547, forpricking and trimming soles.

The object of my invention isto channel the sole just before it ispricked, thus avoiding the now common plan of marking the outer sole andthen channeling itby hand two operationsbefore applying the sole to themachine to be prieked, or pricked and trimmed, as in the said Turnerpatent. v, In this my invention 1 have made one of the under supports orrests substantially such as tally toward and from the other undersupport or rest, and] have also adapted the presser, placed above andcooperating with the movable rest, to slide horizontally with the saidrest whenthe sole is clamped between them, they, in connection with theawl, which will then preferably rest in the work, carrying or feedingthe sole forward against a stationary chan-I nel-cutter, the upper endof which is extended upward into and just above the top of the movablerest, the forward movement of the sole of the lasted shoe against thiscutter forming a channel in the sole a little in advance of theawls,the1ine of the channel being defined by the outline of the lasthaving the upper of the lasted shoe upon it, as the line of pricking andtrimming is determined in the said Turner patent. The lip of the channelturned over in advance of the operation of the awl is kept out of theway of .the awl by means of a channelopener at the side of the rearmostunder support or rest. The presser-foot above the rearmost rest isthrown down upon the material to clamp and hold it firmly while the awland the forward presser-foot and under support or rest move backwardafter having fed the material forward.

In this application I have considered it necin the claims.

those parts which are common to both machines.

My invention consists in a machine of the class herein shown andspecified for pricking and trimming soles when provided with achannel-cutter; also, in details of construction, aswi'll be hereinafterdescribed, and pointed out Figure 1 represents a front-side elevation ofa sufficient portion of a sole pricking and trim- ,ming machine toillustratemy invention, the

right-hand end of the machine being mostly broken away to clearly showthe lever and cam on the main shaft, which operate to raise and lowerthat one of the presser-feet located above 7 the rearinost under supportor rest; Fig.2, a front-end view thereof, both presser-feet being liftedand the movable rest being moved for- 0 ward; Fig. 3, a top view of theunder supports or rests, with themovable rest forward, the upper end ofthe channel-cutter being shown in the slot or the said rest; Fig. 4,details of the channel-cutter; Fig. 5, details of the channelopener;Fig. 6, a top view. and section of a piece of sole-leather cut,pricked,and channeled, as it will be by myimproved machine; and Fig. 7shows the awls and cutters and their carriers detached from the machineQThe sliding carriage (1, having two uprights, 0?, to receive the pin 8for the carriers d at, provided with the two awls l0 and the two chiselsor cutters 11 and the sliding cam bar or slide d are as in the saidpatent. Upon this carriage d, by the screws 20, I have secured an arm,A, the forward end of which I have attached by a screw,'2l, to anauxiliary carriage, B, fitted between suitable guides, 22, the saidauxiliary carriage having secured to 0 and extended above it the movablerest 0, which takes the place of the rest 0, shown in the said patent.

In the Turner patent the two presser-feet had only a rising-and-fallingmovement, and 5 were raised and lowered simultaneously, both beingactuated by the lever f and link f therein, made double or forked but inthis my machine the presser-Ifoot D, which takes the place of thepresser-foot f of the said patent, is pivoted at 13 upon the upright E,secured to the carriage d so that the'said presserfoot, besides itsrising-and-falling movement, is moved horizontally backward and forwardin unison with the rest 0, awls 10, and cutters 11. The arm D of thispresser-foot is connected, by link f with lever f corresponding with alike lever in the Turner patout.

The presser-foot f, like that shown in the Turner patent, and havinglike movements, is actuated by means of a'link, F, and the lever F, therear' of which is moved at the proper time by the cam F on the mainshaft 1).

The rearmost under support or rest, 6, for the sole of the lasted bootor shoe to be channeled, pricked, and trimmed (substantially such a restas that in the Turner patent) is secured on a block, B in line with theauxiliary carriage B, and upon the side of this rest 1 have secured byscrew 24 the channel-opener G.

The forward longitudinally-movable rest, 0, before referred to, isprovided with a slot, 25, in which is placed the channel-cutter H, theupper end of which is beveled and sharpened, as shown in Fig. 4, theupper end of the said channel-cutter, extended above the rest 0, cuttingachannel, 0. into theleather or soleh at its under side immediately inadvance of the awl 10. To cut the channel, the sole h is clamped firmlyat bottom and top between the rest 0 and presser D, and is carriedforward against the sharp end of this channel-cutter, a portion of theleather being lifted and turned over to form a channel flap or lip, 28.The parts of the rest 0 each side of the slot 25 so support the sole asto insure a uniform depth of channel; but this channel-cutter may beadjusted vertically by the screws 26, to insure a channel of greater orless depth.

The lip 28 of the channel, after passing the awls, is held open by meansof the channelopener G. This channel-opener also prevents the liabilityof the awl pricking, and thereby injuring the lip which is to cover thestitches in the sole after they have been formed by hand.

To stitch .aloft,-.as it is called in shoe-factories, I may employ achannel-opener shaped to remove the leather and form a groove without alip.

The awls and cutters operate just as in the Turner patent, the former toprick the series of holes it through the sole h in the channel,

and the cutters to cut the leather and give shape to the sole byremoving the surplus leather, as at w.

The springs g g, acting on the carriers d 01 keep the rollers at theirrear ends against the cam-shaped ends of the bar Instead of operatingthese carriers as herein shown and as in the Turner patent, I mayoperate them as in a machine devised by G. W. Gledden.

The upper of the boot or shoe just outside of and resting against thelast, as in the Turner patent referred to, will be held pressed againstthe front sides or faces of the pressers D and f, and the channel andline of awl-holes in the sole and the edge of the sole as formed by thecutters 11 will all be defined from the shape of the last for thepurposes fully described in the Turner patent.

I do not desire to limit my invention to the exact construction ofchannel-cutter herein described.

1 claim 1. In a machine to prick and trim a piece of leather applied toa lasted boot or shoe to form a sole therefor, a channel-cutter to cut achannel in the said leather, combined with an awl to perforate the saidleather through and through from the bottom of the said channel, and acutter to trim the said leather outside the perforated and channeledportion substantially parallel with the direction of the saidperforatioifs and give to it proper shape for the sole of the lastedboot or shoe, substantially as described.

2. The rest 0', and presser f, and the horizontally-movable rest 0, andpresser D, combined with a channel-cutter co-operatin g therewith,substantially as described.

3. The stationarychannel-cutter extended up through a slot in thehorizontally-movable rest, and the horizontally movable liftingpresserD,shaped to bear upon the welt of the shoe and act against the upper onthe last near the welt, to guide the shoe to insure the formation of achannel to correspond in shape to the outline of the bottom of the lastor inner sole thereon, substantially as described.

In testimony whereof have signed my name to this specification in thepresence of two subscribing witnesses.

EDWARD F. WHITE.
